So... any ideas? It's a TCD5400. Perhaps the kernel is not compatible with 8.1?

I don't know what kernel you are using, but it's possible the stock 8.1 usb and/or network modules are not compatible with your kernel. I know on the dual tuner SA model, the stock bcmemac.o is not compatible with a kernel compiled with NETFILTER turned off.

I would suggest you either use the stock kernel (via replace_initrd) with the stock modules or see if the backport usb/network modules will work with the kernel you are using. A little experimentation via a serial console and a bare bash (nothing loaded or running yet) should lead you to a workable combination of kernel and modules pretty quickly.

FYI - I had this happen to my sd-h400 as well. upgraded to 8.1 manually like I always have. It started rebooting and never came up untill I unplugged the usb nic. I was using the 3.1.5 kernel I have used since I removed sleeper. Looking into what is going on now.

Just wanted to chime in with a similar experience. I manually took the 8.1 update on my TCD240 and it also will not boot with my wired NIC plugged in.

It it will boot with my wireless NIC plugged in, but it doesn't initialize nor work. If I try to go to network settings it won't let me see or change any settings because it says no network card detected.

My wired NIC is a DLink DUB-E100 and my wireless is a DLink DWL-G122. I also have a wired Netgear FA120, but havn't tried it yet.

Not related to 8.1, but my wireless NIC (Linksys USB) also stopped working since 7.2 ot 7.3. Since I went wired I tough it was something on my end. Same simptoms, TiVo says there's no network card detected, etc. Now I see I am not the only one, hehe.

got mine to work. used the backport drivers (as I did before upgrade). I didn't have to update the hotplug file, it already had the nic in it. I think the new kernel may have the needed things for the nics.
